Multi-Language (Coding): Merge Two Sorted Lists Test

This coding problem involves merging two sorted linked lists into one sorted linked list. A linked list is a data structure that consists of a sequence of nodes, where each node contains a value and a reference to the next node in the sequence.

The task is to combine the two linked lists such that the resulting list is also sorted in ascending order. This can be done by comparing the values of the first nodes of the two lists and selecting the smaller one to be the head of the merged list. The process is then repeated with the remaining nodes of the two lists until one of the lists is empty.

The candidate will be assessed on their ability to implement efficient and correct code, as well as their understanding of linked lists and sorting algorithms. They should be able to write code that can handle edge cases such as empty lists or lists with different lengths.
